NOTORIOUS hardman Jimmy Holland used a Katy Perry song to describe his feelings for shamed prison officer Christine Robertson in a love letter from behind bars.

The note was among a stack seized by cops from Robertson’s bedside table after they caught her naked in bed with the escaped prisoner.

She was locked up on Wednesday after a jury found her guilty of harbouring Holland when he escaped from Castle Huntly open prison last year.

The letters – released by the Crown yesterday – were a key part of the prosecution case.

In one, Holland wrote: “Just like the Katy Perry song Teenage Dreams that I asked you to listen to, I never thought it would be this way.”

Fiscal depute Douglas Wiseman told a six-day trial at Dundee Sheriff Court that the cards and letters proved a “romantic relationship” between the pair.

The cute characters on many of the cards are a world away from Holland’s hardman image.

He is considered one of Scotland’s most dangerous prisoners.

He has racked up more than 40 years worth of jail terms in a 25-year criminal career that has included armed robberies, hostage takings, prison riots, stabbings and gun crime.

Holland, 41, has even boasted of his sickening violence in two books – Scottish Hard B*****ds and Lost in Care.

In the letters, Holland describes Robertson as his “best pal, lover and all round bag of laughs”.

One includes an autograph from Formula 1 racing legend Jackie Stewart – given to Holland when Stewart visited Saughton prison in Edinburgh during a dyslexia campaign.

In another letter, he calls Robertson, 45, “the most gorgeous special girl in the world” and tells her he “fell in love” with her “the second” he met her.

He also says they are “soulmates” – and tells her he will “take her hostage and spank her peachy bum”.

The thug outlines his life of crime and offer’s to attack Robertson’s ex-partner.

He insists he is “not an animal the way the screws make me out on paper” and talks about watching The X Factor and EastEnders behind bars.

The love notes refer to Robertson as “Ginger” and he signs off as “Jimmyboy” and “honeymonster”.

Jurors heard details of the letters during the trial.

They were also told of text messages sent between the pair – including one, sent by Robertson to Holland a week before he escaped, that stated: “I want you too in a nice clean silky bed – only one thing missing is you.”
